The Lada Largus model is a joint brainchild of the designers AvtoVAZ and Renault-Nissan. Its design is based on the popular universal public car Dacia Logan MCV. When creating this car, the main focus was on the category of practical and family car enthusiasts, because the set of technical and operational features of the model fully correspond to its image.
The basic version of the equipment of the Lada Largus implies the presence of a standard radio, which the Korean company Daewoo kindly shared with Tolyatti residents. However, sometimes the firmware of the radio is required. In addition to the head unit, the developers addressed 4 loudspeakers located around the perimeter of the interior space, or rather in the door panels. Owners notice that this device fits harmoniously into the interior and has quite simple and convenient functionality. All controls and buttons are intuitive and do not cause “stupor” even for “wild” drivers. The high-quality fit of all components of the audio complex is also noted, since during operation it was not possible to find any backlashes or squeaks in the buttons.
To study in detail the full range of functions of this radio and how to control them, you should watch this informative and useful video:
Note that the consumer radio kit includes convenient instructions, which are designed to provide a quick acquaintance with the device and its functionality. In this article we will tell you how to unlock the Largus head unit.
Functions of the standard Largus audio radio
The audio device that is present in the Lada Largus allows the owner to acquire such useful options as:
- search and memorize radio stations broadcasting in the traditional FM or AM bands;
- the ability to display the names of tuned stations with a convenient “RDS” function;
- playback of audio programs recorded in the following formats: “MP3” and “WMA”, as well as “AAC” and “WAV”;
- connecting external sources to the head unit for the purpose of subsequent playback of information programs through standard speakers (for this, the radio has “USB” and “Jack” connectors, as well as a “Bluetooth” option;
- switching with the “Hands Free” wireless kit, which allows telephone communication with subscribers while driving.
Also, we should not forget about the presence of a security coding function in the radio, which allows you to increase the degree of protection of the device from theft attempts.
How to speed up the process of searching for information
Finding out the information you need will take some time. Repair of radios “Ford”, “Ford Focus”, “Renault”, “Nissan” and so on will have to be postponed for a while. If warranty service is provided, it is better to immediately contact the appropriate service center so as not to damage the integrity of the case. Radios in Ford, Nissan, and any other car are common equipment that should be repaired free of charge and help with setup. But drivers often do not use the guarantee. Finding a responsible representative is problematic, and any other radio repairman will ask you to find out the code.
In most cases, you can find out the radio code by the serial number. In order to find out the serial number, you need to pull it out of the hole. The serial number is indicated on its reverse side. The photo shows exactly where to look for it.
It should be immediately reported to the manager of the organization, as well as detailed information about yourself, and describe the problem with the radio. It is best to report that the radio simply needs repair. In such a situation, each person has the right to choose a master. The questions are unnecessary - someone should tell you the PIN code. If the manager knows for sure that the legal owner wants to know this combination of letters or numbers, he will be able to communicate it with a clear conscience. But the serial number will not always help to achieve the truth. Sometimes it is much easier to find out the radio code by the VIN code.
VIN code - what is it?
The VIN code of a car is almost impossible to fake. More precisely, there are no known precedents. This is an effective element of protection. The VIN code will help you find out if the car is stolen. It is indicated in the documents for the car, most often in the registration certificate. It is also on the body. The photo shows where it can be applied.
If the manager with whom you are talking demands to pay for services or refuses to provide information, and the radio needs repair, it is better to provide the VIN code. Perhaps it will become a powerful argument. You can always record the conversation. Rudeness, tricks, cunning - all this will only irritate when information is needed, identity is confirmed. The radio will be quickly repaired if you choose the right tone for the conversation and prepare for a negative reaction to the call.
It is incorrect for the manufacturer to demand payment for PIN code information - in this case, the consumer’s rights are violated, namely, his freedom of action when choosing a repairman. Conflicts, of course, are something few people enjoy. And yet you must be able to protect your rights from someone else’s incompetence and negligence. The bad mood of the person with whom the conversation is being conducted should not in any way affect the quality of the service. Companies often do this - they record a conversation with a client. The client can do the same thing - record the conversation, collect incriminating evidence, and use it.
The standard head unit used on the Lada Largus has a security code that must be entered after the battery is disconnected or the fuse in the power circuit fails. The password is printed on a separate insert in the service book, which is given along with the car upon purchase. If documentation is lost or the head audio unit is replaced with an analogue one, the owner needs to know how to unlock the radio on the Lada Largus.
Coding of the original car radio
The standard Lada Largus device contains a set of protection functions that allow you to block attempts to turn on in cases where:
- the power supply from the on-board network (battery) is disconnected;
- the fuse-link protecting the device burns out;
- The radio is directly disconnected from the local power supply.
To be able to turn on a locked radio, you will need to enter a special four-digit code key. This code for the radio may be present in the service documentation attached to the device itself or simply be communicated to the owner at the time of purchase in the showroom.
Note that the code for the radio is entered using the keyboard, which is located on the front panel of the device.

What to do if the PRE CODE cannot be found?
Enter the code. Step-by-step instruction
How to enter the code step by step. The input process itself involves following this sequence of manipulations.
- We turn on the Lada Largus radio by pressing the “1” button in the keyboard field. In this case, an inscription appears in the form of “CODE” with the numeric dial “0000”. The first digit character will be in flashing mode.
- Now, by pressing the “1” button, we achieve the first digit to appear on the display.
- Entering the next digits in the code line is carried out in a similar way. However, this will require pressing the keyboard buttons corresponding to the serial number of the code digit (“2”, “3” and “4”).
- Once you have completed entering all four code characters, you will need to press and then hold the “6” button, also located in the keyboard field.
- Immediate unlocking of the radio will indicate that the code on the radio has been entered correctly.
Important! When the radio code is entered incorrectly, a message in the form of “CODE ERROR... WAIT” is displayed on the screen, after which a 2-minute time delay will be required. Then you can start re-entering.
Each subsequent input attempt, if it turns out to be incorrect, requires a shutter speed twice the previous time interval, etc.
Radio malfunctions and methods for diagnosing them
As you know, the Lada Largus is equipped with an audio system with a set of speakers already from the factory (depending on the configuration). The amplifiers are located in the front and rear door panels. To connect non-original speakers, several wiring harnesses are provided (including for increasing power using an amplifier when connecting a subwoofer). Since the connector plugs do not comply with the current standard, to connect another head unit you will need to additionally purchase adapters.
A standard car radio sometimes brings not only the pleasure of listening to music, but also some problems. The device may not work or function incorrectly for various reasons. In general, the list of faults includes only those that an ordinary driver (without special knowledge of electrical engineering) can fix with his own hands, without the need to contact a specialized center.
When it comes to repairs, it can often be cheaper to replace the device. Especially considering the availability of alternative options in different price categories and with different capabilities. At a cost of no more than 6,000 rubles, repairs can cost half this amount.
Main problems
If, when you press the power button, the head unit does not respond and does not turn on, then first of all you should pay attention to the mounting block, checking the 15A fuse in socket F28. Through it, the electrical circuit of the device’s memory is connected with the saved settings.
The mounting block cover is located on the front panel on the left side at the end. You can understand that this fuse has blown by the absence of signs of operation of the instrument cluster panel, interior lighting and trunk lighting, since their electrical circuit is also powered by F28. If the fuse has not blown, the next check point will be the condition of the connecting contacts and the integrity of the wire that goes from the fuse to the A4 power connector on the back of the radio.
A common problem is no sound, i.e. the device itself turns on but there is no sound coming from any of the speakers when playing music.
In this case, the fault may also be the fuse, but F38. It supplies power to audio output devices. A faulty fuse is also indicated by a non-functioning cigarette lighter. If the latter works, then the fuse is intact. The lack of sound can also be caused by a violation of the integrity of the wire running from the fuse to connector A7 on the radio. And if only the rear speakers do not work, the culprit may be a broken connection in the block, which is located directly behind the driver's seat between the front and rear doors.
The cause of the malfunction may be the absence of ground - this is the black wire going to the radio (terminal A8). In all other cases, intervention in the electrical circuits of the device will be required. Without appropriate knowledge in this area, there is a high probability of complete failure of the radio. When contacting specialists, repairs can cost at least 1,000 rubles, not counting diagnostics.
Removing and installing the radio
If a device fails, you will need to dismantle it to install another one. Removal will also be necessary if it is necessary to connect speakers, repair, clean terminals or reflash. Visually, there are no latches or keys for removal on the front panel.
In fact, on the front of the radio there are four holes into which you need to insert 4 rods of suitable diameter (about 2 mm). The dismantling process is as follows.
- Two rods are inserted into the holes on the left side.
- Two more - on the right.
- Now you should simultaneously press all the rods at once.
- At the same time, pry it with a suitable plate, for example, a plastic card.
- After characteristic clicks indicating that the latches are loosened, you can remove the device.
Installing the radio is even simpler: just insert it into the mounting socket and press until the latches fit into the grooves.
How to decode the head unit
The procedure involves determining the radio code, entering which allows you to activate the head unit in the Lada Largus. Such actions should be resorted to when the word “CODE” appears on the display, and the owner does not know its digital version. Let's consider the option of how to unlock the radio, as well as how to enter the code correctly.
Here you will need access to a special code generator applicable to Renault and LADA Largus radios. You can get this service by registering for free on the corresponding website on the network.
The decoding process involves an algorithm consisting of several stages.
- We simultaneously press and hold the “1” and “6” buttons present on the keyboard (for 5-6 seconds).
- After this, the display will display the inscription “pre code xxxx”, where the last four characters indicate that same “pre code”. It is necessary to gain access to the secret code combination, by entering which the radio will be instantly decoded. The radio code itself is formed from one letter and 3 numbers.
- If this operation fails, you will need to dismantle the radio. For this purpose, you need to acquire two pullers “7711381821” or four pins. These devices are inserted into special holes present on the front panel of the audio device. Simultaneous pressing on the integrated removable components allows you to remove the radio from the landing shaft. Now disconnect the cable connector and antenna wire.
- There is a sticker on the back wall of the device on which the manufacturer has applied a special barcode and other information related to this product. There you can also find the same “PRE-CODE”.
- We go to a site with a code generator and enter the “PRE-CODE” read on the sticker into a special window for this service.
- Now we confidently click on the “Generate” button, after which we get the code we need.
- Next remains the method indicated by us to enter encoded information into the radio.
Attention! Before dismantling the device, we recommend disconnecting the power supply by removing the terminals from the corresponding terminals of the LADA Largus battery.
See:
There are times when the standard radio has a bunch of barcodes, a bunch of numbers, but the required composition (1 letter, 3 numbers) is nowhere to be found.
To do this, try using an application for Android and iOS devices to read barcodes.
Read all the barcodes in order and find the acquired results by searching on the Internet; in the acquired data you may find the combination that suits us - PRE-CODE.

Largus car radio firmware
When the owner of LADA Largus is dissatisfied with the standard functionality of the radio, then you can resort to firmware. The reasons prompting such actions may include failures of configured programs, failure of buttons to respond to the activation of specific functions, etc.
Important! When flashing the firmware of the radio, you should remember the responsibility for the subsequent performance of the LADA Largus radio. This operation is quite complicated and no manufacturer will provide warranty service for the radio if the owner decides to take such measures as flashing the radio's firmware. When an irresistible desire arises to carry out the firmware procedure, it is better to entrust it to specialists who have considerable experience in this field. Now you know how to unlock the car radio, as well as how to enter the code correctly.
How this is done can be seen in the video:
How to enable test mode?
This “trick” was present in Logan, and then successfully migrated to LADA Largus. To activate the self-diagnosis mode, perform the following list of manipulations:
- We turn off the engine.
- Click on the button present on the panel and hold it.
- Turn on the ignition and continue to hold the designated button for a few seconds.
- At this moment, the following picture is observed: the arrows on the instruments begin to “run,” which indicates that the mode is activated.
- Now we move on to periodic button presses again. The screen displays various symbols and meanings, including:
- the number of liters remaining in the tank (the information will be correct if the car is currently on a flat section of the road);
- firmware version;
- codes corresponding to certain malfunctions (errors), etc.
To exit this mode you just need to turn off the ignition
Why is this mode necessary? First of all, it allows you to obtain important information about error codes. Their subsequent decoding will allow us to determine the malfunction in the LADA Largus car in order to quickly eliminate it
